Intro Skipper (beta)

Analyzes the audio of television episodes to detect and skip over intros.

⚠️ Warning for Jellyfin 10.9 ⚠️

The current version is a beta version, so please save your old files before upgrading from 10.8 to 10.9. Changes are possible during the beta phase!

System requirements

• Jellyfin 10.9.0 (or newer)
• Jellyfin's fork of ffmpeg must be installed, version 6.0.1-5 or newer
  • jellyfin/jellyfin 10.9.z container: preinstalled
  • linuxserver/jellyfin 10.9.z container: preinstalled
  • Debian Linux based native installs: provided by the jellyfin-ffmpeg6 package
  • MacOS native installs: build ffmpeg with chromaprint support (instructions)

Detection parameters

Show introductions will be detected if they are:

• Located within the first 25% of an episode or the first 10 minutes, whichever is smaller
• Between 15 seconds and 2 minutes long

Ending credits will be detected if they are shorter than 4 minutes.

These parameters can be configured by opening the plugin settings

Installation

Step 1: Install the plugin

1. Add this plugin repository to your server: https://raw.githubusercontent.com/jumoog/intro-skipper/master/manifest.json
2. Install the Intro Skipper plugin from the General section
3. Restart Jellyfin

Step 2: Configure the plugin

4. OPTIONAL: Enable automatic skipping or skip button
   1. Go to Dashboard -> Plugins -> Intro Skipper
   2. Check "Automatically skip intros" or "Show skip intro button" and click Save
5. Go to Dashboard -> Scheduled Tasks -> Analyze Episodes and click the play button
6. After a season has completed analyzing, play some episodes from it and observe the results
   1. Status updates are logged before analyzing each season of a show

Troubleshooting

Scheduled tasks fail instantly

• Verify that Intro Skipper can detect ffmpeg with Chromaprint
  • Dashboard -> Plugins -> Intro Skipper -> Support Bundle Info
• Verify that ffmpeg is installed and detected by jellyfin
  • Dashboard -> Playback -> FFmpeg path
• Verify that Chromaprint is enabled in ffmpeg (--enable-chromaprint)

Skip button is not visible

• Verify you have successfully completed the scheduled task at least once

• Clear your browser cache and reload the Jellyfin server webpage

• Fix any permission mismatches between the web folder and Jellyfin server

  • Docker - the container is being run as a non-root user while having been built as a root user, causing the web files to be owned by root. To solve this, you can remove any lines like User: 1000:1000, GUID:, PID:, etc. from the jellyfin docker compose file.

  • Install from distro repositories - the jellyfin-server will execute as jellyfin user while the web files will be owned by root, www-data, etc. This can likely be fixed by adding the jellyfin user (or whichever user executes the jellyfin server) to the same group that owns the jellyfin-web folders. You should only do this if they are owned by a group other than root.

Installation (MacOS)

1. Build ffmpeg with chromaprint support using brew:
   • macOS 12 or newer can install the portable jellyfin-ffmpeg

brew uninstall --force --ignore-dependencies ffmpeg
brew install chromaprint amiaopensource/amiaos/decklinksdk
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-chromaprint
brew link --overwrite ffmpeg

2. Open ~/.config/jellyfin/encoding.xml and add or edit the following lines
   • Replace [FFMPEG_PATH] with the path returned by whereis ffmpeg

<EncoderAppPath>[FFMPEG_PATH]</EncoderAppPath>
<EncoderAppPathDisplay>[FFMPEG_PATH]</EncoderAppPathDisplay>

4. Follow the general installation instructions above
